I summarized your posts to show that there really isn't much useful information in them. For you and the people responding. You're about to replace parts that probably don't need replacing. That's expensive. You didn't say how many miles are on the engine, when the last tuneup was, or if it's an automatic or manual.

I'm not positive but I think 2016 has idle speed control in the electronic throttle body. Today's computer controlled engines use the PCM to maintain idle speed, by opening idle air control. If the engine runs fine when driving then the PCM should be able to maintain a proper idle RPM. If it can't you should get a code.

I don't think that you have a coil problem.

 

Makes sense. My truck has 67k miles on it and it’s automatic. I get all of your typical maintenance done on it that Ford suggests. Never had a problem with her until now. I’m going to run it to a shop tomorrow and we can go from there. Thank you for the last post though in terms of the throttle body. I’ll be sure to mention that when I take it in tomorrow.

 

Also- some more information that might be of use. When the engine turns on at a cold start, it has no issue. It has a strong idle. When the engine is warmed up, this is when it happens.

 

I looked around for idle control videos and found a few. Here's one that has many interesting comments. Seems like a common problem that is difficult to diagnose. People reporting many different causes. Good luck at the shop, hope they have some good people there.

Read these comments. Everything from changing the oil to fan plugs (not kidding) to fuel pump driver modules to VCT phasers.

 

Went to Autozone after work and no codes came up on the report. Going to take it to a shop tomorrow for more extensive review.

Thank you for the feedback. No DTCs found at Autozone so to me that rules out coil packs.

More sophisticated diagnostics at most well equipped shops will likely locate your issue.

 

Try cleaning the map sensor ontop of the intake manifold, then the sensor before the throttlebody, and the one after the air filter. Use a non chlorinated electronics spray cleaner. Local autozone has em on the shelf.

 

If the sensors are dirty, they cant take proper readings and maybe the cause of the stalling. If you have a k&n oil type air filter, the oil in it sometimes gets sucked up and coats those sensors. With the pvc system circulating bottom end air into the manifold, i bet that its coated the said map sensor.... this will be the cause of some hard shifting and stalling.

 

MAP = Manifold Absolute Pressure sensor
MAF = Mass Air Flow sensor

 

Yep
